Dear Community,

When i upgrade my RM510QGL FR2 unit to a new firmware, the at+cfun=0 or at+cfun=1 return errors while i wasnt experience this when running on the built-in version (RM510QGLHAAR11A01M4G_BETA_20200801), i dont know what went wrong, the update itself or the firmware, could I revert to that old version or can someone provide me with the new firmware version with steps on how to do it properly.

Thank you in advance
Imax
